In this paper, we show that the stabilizer subgroup of Df = {a ∈ Fq | f (a) ∈ (F×q )2} for a f ∈ Fq [x] without multiple roots can be derived from the stabilizer of Df = {a ∈ Fq | f (a) = 0} ∪ {∞}. As an application, we construct a family of 3-designs such as 3 − ( q + 1, q−1 2 , (q−1)(q−3)(q−5) 16 ) , where q is a prime power such that q ≡ 3 (mod 4) and q… (More)

In this paper, we slightly improve the Baby-step Giant-step for certain elliptic curves. This method gives the running time improvement of 200% in precomputation (Baby-step) and requires half as much storage as the original Baby-step Giant-step method.
